追加结构以创建新的结构集(如果存在) [英] Appending structure to create new set of structure if exists
问题描述
我正在检查表单值,如果结构中存在其他表单值,则应附加其他值,并应创建该会话结构.使用以下代码,我正在尝试执行此操作:
I am checking the form value and if the different form value exists in the structure, it should append it else, it should create that session structure. With the following code, i am trying to do it:
<cfif session.box_status.partner_id NEQ "">
<cfset session.box_status.partner_id = StructAppend(session.box_status.partner_id,FORM.partner_id,'No') />
<cfelse>
<cfset session.box_status.partner_id = FORM.partner_id />
</cfif>
显然,上面的代码没有检查表单结构中是否存在相同的值,但这也给我一个错误:
Apparently above code does not checking if the same value is existing in the form structure or not, but it is also giving me an error:
You have attempted to dereference a scalar variable of type class java.lang.String as a structure with members.

推荐答案
您正在将session.box_status.partner_id视为结构,但这是一个简单的值.会话是一个结构,但是您要特别使用的值是一个简单的字符串.只需使用listAppend.
You are treating session.box_status.partner_id as a struct, but it is a simple value. Session is a struct, but the value you are particularly working with is a simple string. Just use listAppend.
在评论中更多地谈论了Voeger之后,我们发现他想要一个数组结构.因此,他应该首先将值初始化为数组:
After talking more w/ voyeger in comments, we figured out he wanted an array of structs. So he should begin by initializing the value as an array:
session.box_status = arrayNew(1);
或
session.box_status = [];
然后他可以追加一个结构.
And he can then just append a struct.
newData = { // keys here };
arrayAppend(session.box_status, newData);
